Claims. 1

lhis invention relates to apparatus that indicates various conditions in the oil circulating system of a motor or in other liquid circulating systems.

One object of my invention is to provide apparatus that indicates the pressure of oil circulating in a motor, hence showing whether 01' not changes should he made in the oil or other parts of the system.

Another object is to provide apparatus by which the condition of the oil, as indicated by its color, can be compared with a color chart, to instantly check its condition.

A further object is to so paratus that its operation is simple and certain, and so that an inexperienced person could tell what conditions are in the oil circulating system.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construc tion, combination and arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited. to the construction disclosed by the drawings nor to the par icular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my claims.

In the drawings:

Figure 1 is a front elevational view of my apparatus. Figure 2 is a top plan view thereof. Figure 3 is a sectional view taken on the line 3-3 of Figure l.

[is illustrated, my apparatus has a supporting means which as shown, includes a circular frame Iii to which a supporting staff It is attached by a connecting T 53. This stail may be attached to a floor stand, if desired. A name plate I4 is shown attached to said supporting frame H! by clamps it.

My indicating gauge G, which is supported by said supporting means, has a bottom member If! later described. A glass or transparent tube 26 rests on said bottom member. Lower straps 24 are attached to said frame it and said bottom member !8. Said tube has a top cover 22, and it is ltept in vertical position with the aid or" upper straps it; that are attached to a plate Ill and to said frame it It is ordinarily circular in cross section and extends perpendicular- 1y upward with relation to said bottom member.

Said gauge has a face member 28 attached to said frame ill, as by cement or solder, on which various indicia appear as later described, to which face member 28 said plate 21 is attached.

A conduit 30 is in communication with'said bottom member 58 at one side, which conduit extends to and communicates with the oil line or circulatory system when in operation. At the other side of said bottom member another conduit ti connects with said bottom member [8 and may communicate er part of said oil line.

construct said apwith an oil iilter or anoth 2,672,756 PATENT QFFICE Within said tube 20 is a spindle 33 that tapers in width upwardly, being shown as an elongate cone, and which is spaced from said tube 26 laterally at all points so oil may flow and accumulate between said tube and spindle between the top and bottom thereof. Said spindle 33 has a hole or bore 35 extending longitudinal- 1y therethrough which. is in communication with said conduit 3| whereby oil enters therefrom into said spindle t3 and flows therethrough and out of the discharge portion 36 of said hole iii which is near the top and at the side of said spindle. Thence the oil passes downwardly in the space between the said tube 25 and spindle 33 and between the float and spindle. Thence it may pass out of said conduit 30 to recirculate in the oil system of the motor. Said conduit 30 has a capacity available for the flow of liquid less than said hole discharge portion 36.

Since ordinarily some oil will accumulate in said tube 20 it will have the effect of raising a float 353, that preferably is spool-shaped exteriorly as shown and which has a hole through it whereby it is movably mounted on said spindle 2!). Said float preferably extends almost to the side of said tube 23 and its outer edge is preferably dished as at :22 so that oil outside of it, between its top and bottom edges may be more clearly seen. The taper of the spindle 33 serves to vary the cubic capacity of the tube 2%. The reduced capacity of said tube at the lower portion assures relatively quick movement upwardly of the float .38 when it is at the bottom or lower part of said tube. The increased capacity at the upper portion assures a slower movement of the float the higher it ascends.

A. guide line 44 is marked on said float 38 to better identify the exact position of the float with respect to the markings on said gauge face 28, as explained later.

At the right of said tube may be provided on a color chart it said gauge face 253 divided into rectangular sections by the horizontal lines shown. Each section i colored the same color as oil in a motor in varying conditions. For inthe lowest section is colored the same as the color of new oil. The next section above has a color the same used oil which should be checked for its impurities. The top section has color my oil which. should be changed. To (.letermine the condition of the motor oil, impurities are concerned, one only has compare the color the oil in said tube 20 with the various colors appearing on chart Outside to the right of color chart M5 is a scale of figures to indicate the ressure of the oil in the circulating tem, Vr'iliCh termined by the position of at the left of s d is a chart 5% which indicates the condition of the oil filter'cart:

Of course, these scales and charts are convenient rather than indispensable; since th e po My apparatus'is used by connecting it 'to'the oil circulatory system of a mot'orfor the sole purpose of Tdetermining"conditions" iirsaid oil system as explained."
